    My audio sources has 200mv balanced output. Will it overload the XLR inputs?
    Connie T on Aug 28, 2017
    BEST ANSWER: A millivolt is a thousanth of a volt, so 200mv is 0.2v. I wouldn't plug an audio source into the microphone xlr inputs. Use the auxiliary that is on the system. I believe there are 2 or 3 inputs that are labeled for aux.
    What is the warranty of this unit? I can not seem to find it on the website or in the user's manual when downloaded.

    BEST ANSWER: Thank you for your interest in our Commercial Audio products. This is an over site that will be corrected. All Monoprice components have a 1-year warranty.
    Building out a doctor's office with approximately 24 in-ceiling/in-wall speakers for background noise. Will your 120W amp work for this scenario? Will I need to purchase an additional step-down transformer on the speaker end that convert the signal back to a normal speaker level ?
    New User U on Dec 11, 2017
    BEST ANSWER: This amp will handle 70 or100 volt speaker system if the speaker you purchase are 70 volts with a 5 watt tap or lower IE 3 watt. Then you build a speaker system with 24 speakers. This amp is rated at 120 watts so it will handle 24 speaks@5 watts.
    Im looking to run 15-20 6 in jvc 8 ohm speakers with transformers. what size should i consider, 120w or 240W?
    New User U on Sep 11, 2017
    BEST ANSWER: Thank you for your interest in our commercial audio products. The manual for this product is available for download from the product page. It explain how the math for 70V speaker works in a safe manner. Basically when you decide what power tap you want to use for each speaker. Most transformers will give you 2-4 options. If the JVC's are 30W RMS @ 8Ω the you may have 30W, 15W & 7.5W taps. Let's say you use the 15W tap on 15 speakers then the total power from the amplifier will be 225W. Any amp running 70V should only run 80% of max power to ensure long uninterrupted service. Our 240W models should only run 192W max. You will need to run some at 7.5W like lavatories and shorter ceiling areas so people are not blasted.
    Will it struggle with heat when used with 2 100 or 200 W - 70 volt outdoor speakers?
    Michael W on Apr 24, 2017
    BEST ANSWER: This amp is only rated for 120W. It is better for long term use to give your self 20% headroom. This means your should only run about 98W total power. For 2 x 100W horns you should look at out 240W version of the mixer/amp.

    I have a 2000 sq ft office and I am looking for a system to run background music. It has 6 rooms and I would like 6 in ceiling speakers. How do recommend I build a music system for this need?
    Jimmy A on Feb 1, 2017
    BEST ANSWER: Our Commercial Audio 120W 5ch Mixer/amp is a great choice for this exact scenario. You can easily connect 6 of our Commercial Audio 70V Ceiling speakers in parallel to the 70V output. Use 14888 4" speakers for size limitation or 14887 6.5" speakers if you want better bass response. Connect your music source to the RCA's on the back and enjoy the music. You can plug our 14891 paging mic to the front mic input if you need to make announcements and the music will automatically attenuate until you are finished.

    This is nothing fancy but does the job. Replaced old Bogan amplifier for a softball complex. Coaches and team are satisfied.

    Nice price, easy setup
    This replaced a truly ancient PA. Setup was simple and the only problem was due to the wire gauge of our inplace speakers. Other than that? 5 min max install.

    Just what I needed
    Bought this Amp for a really cheap customer. To my surprise this amp blew me away. Works great. For the price you can't beat it. I will be buying this amp again. Works very well with 70v speakers and sub.

    Great quality. Does all it promises.
    I got this unit as part of a component approach to improve and update an aging audio system for the funeral home I work for. It delivers all we need and then some at an unbeatable price point. Coupled with a monoprice 4 zone speaker selector, It is driving two sets of Bose 161 speakers in seperate but adjoining rooms, wired and wireless mics, cd player deck, and a bluetooth receiver. All with power to spare. Solid construction. Couldn't be more pleased with it.

    Great amp, wish it had pass-through
    I'm using this amp to drive an exterior 70v set of speakers in my back yard. It works like a charm, and looks great. It has an internal fan that kicks on when you get up to more serious amplification, but unlike another amp I tried, it stays whisper quiet at normal levels.

    The only thing I wish it had, is a pass through of the input sources. The RCA stereo outputs are amplified as well, which seems like an odd choice. To compensate, I added a $14 splitter on the input source, so the audio could also feed to my interior sound system.
